Importing of 3D DWF - Vista x64

[David Haynes]

Having problems importing 3d DWF into QTO. It stalls at the import - never completes the import of 3D dwf. I have a 64 bit Vista machine. Using Revit Architecture 2010.

David,
I'm having the same trouble. I sent a request in to Subscription and haven't heard back. I've intalled QTO on three machines and it is doing the same thing on all machines. I'm thinking it may have something to do with the Graphics Card, maybe, since DWF are driven off of Open GL? If you hear anything, keep me updated too. Thanks.

It appears (thanks Jason Dodds) that it is a video card issue (mine is nvidia 570m). Autodesk is aware of the problem.
